Laser-to-ion energy conversion efficiency is important for ion-beam driven inertial confinement fusion. We propose to use a suitable plasma waveguide to enhance ion acceleration driven by an ultrashort ∼1021 W cm−2 laser pulse. Three-dimensional (3D) particle-in-cell (PIC) simulations show that, compared with that of the standard planar target, more than an order of magnitude increase of the maximum ion energy and energy conversion efficiency is possible. In particular, with a laser of intensity W cm−2, duration 26.7 fs and energy 0.85 J, 3D PIC simulations show that one can obtain 46 MeV protons and 150 MeV carbon ions, and ∼15% laser-to-ion energy conversion efficiency.

Magnetic reconnection driven by laser plasma interactions attracts great interests in the recent decades. Motivated by the rapid development of the laser technology, the ultra strong magnetic field generated by the laser-plasma accelerated electrons provides unique environment to investigate the relativistic magnetic field annihilation and reconnection. It opens a new way for understanding relativistic regimes of fast magnetic field dissipation particularly in space plasmas, where the large scale magnetic field energy is converted to the energy of the nonthermal charged particles. Here we review the recent results in relativistic magnetic reconnection based on the laser and collisionless plasma interactions. The basic mechanism and the theoretical model are discussed. Several proposed experimental setups for relativistic reconnection research are presented.

Enhanced target normal sheath acceleration based on the laser relativistic self-focusing

et al. 2014

The enhanced target normal sheath acceleration of ions in laser target interaction via the laser relativistic self-focusing effect is investigated by theoretical analysis and particle-in-cell simulations. The temperature of the hot electrons in the underdense plasma is greatly increased due to the occurrence of resonant absorption, while the electron-betatron-oscillation frequency is close to its witnessed laser frequency [Pukhov et al., Phys. Plasma 6, 2847 (1999)]. While these hot electrons penetrate through the backside solid target, a stronger sheath electric field at the rear surface of the target is induced, which can accelerate the protons to a higher energy. It is also shown that the optimum length of the underdense plasma is approximately equal to the self-focusing distance.
